When an image copied from one PDF and pasted to another PDF, it always got pasted in place and with the same size. However, now what happens is: 1) the pasted image position is always in the centre of page. 2) the image is smaller in size, then when I scale it to be bigger, the quality is very pixelated.

This issue never happened before. I've always used the same Acrobat.

Please fix this ASAP!! It is very annoying. Thank you
